I had a 4 horn system originally but it didn't have a deep sound at all but these do. As a 2 horn set they really sound alot closer to the sound you hear on the diesel pusher motorhomes and semi's. They are mounted under my truck connected the the bracket holding my steps boards so get weather and water but keep on going Highly recommend and I would buy them again

The Hadley H00640R is a metal air horn kit with the classic Hadley sound. No fog horn, more of a train horn sound. Mounted easy. Plumbed air to it and installation was complete. Horn did not come with air supply fittings.

This horn is solidly built and heavy. No plastic trumpets here. The sound is just right, neither to high or to low in tone. Sounds like a truck horn should. Im opetating the horn on compressed nitrogen cylinder at 120 psi and it produces 118.7 decibels. I was hoping to run at 150 psi but the solenoid valve i bought wont work at that pressure.

Hadley Horns are pretty good quality, they've been used on Mack trucks for years. It has a very unique sound that definitly can be heard. This type of horn is also known as the Hadley Bully, it is made of metal and typically an undercab style horn and a mounting bracket is needed to mount this to the bottom of a vehicle. I attached this to the bottom of my Chevy S10 with a mounting bracket off of a Mack MRU garbage truck and installed an air compressor and a 12 volt solenoid valve to operate it. It sounds awesome!

Compact design, great sound. Replaced stock air horn on Freightliner M112 with these mounted in the original location. Very happy with the sound.

Tiese are exactly what we needed, loud enough to get inattentive driver's attention.
